Flip it around.
  1. You're in a death handler.
  2. You have no idea why you're there.
  3. Since it could be any reason, you have very little that you can count on.
  4. By using $^M, you have a certain amount of memory you can work with that you can count on. This is to make sure that your death handler will still work if you ran out of memory.
  5. It has no purpose otherwise. It doesn't provide any protection against other reasons you might be in a death handler.
  6. The chance it will be useful is OS and app dependent.

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
